Answer to Question #86380 in Atomic and Nuclear Physics for Tanko Miyabe

Question

1kg mass placed on the moon will weigh

Answer 1

Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object.

Mass unit is Kg.

Weight unit is Newton (N).

Weight of 1Kg matter in Earth is 1 x 9.8 N = 9.8 N.

Weight of 1Kg matter in Moon is 1 x 1.622 N = 1.622 N.

But the Mass of 1 kg object is same in Earth & Moon.

The Mass of an object doesn't change when an object's location changes.

Weight, on the other hand does change with location depends on the gravity.

So the answer is : Weight of 1Kg on the surface of moon is 1.622 N.
